Selected translation of the Chinese characters on the walls:
Civilized Linyi. Less children more pigs. Safeguard social stability. To govern the country according to law. Love the party, love the country, love the people. To build harmonious society. One over-birth, whole village sterilized. No petition, to be a good citizen.
